| 摘 要： | 研究了无性系、杂交组合、半同胞3种不同类型的油茶良种枝梢生长特性,结果表明:油茶叶片分为1年生和2年生,前者占55%,后者占45%,且3种不同类型良种的叶片构成比例基本一致;1年生枝条长度比2年生枝条少2 cm;1年生枝条分枝角度约42°,2年生枝条分枝角度45°.油茶叶片数、枝条长度、分枝角度的变化规律3个类型的良种基本保持一致.平均每枝挂果数,无性系最多,杂交组合次之,半同胞最少.结果还发现油茶枝梢生长指标之间存在一定的相关性,同时对冠幅、单株产果量、鲜果含油率也产生影响.

| Abstract: | The Shoot growth traits of improved varieties including clones,hybridization combinations and half-sibs were studied to developmental regularity of shoots of oil-tea camellia in this paper.The results showed that the leaves of oil-tea camellia could be classified into one-year and two-year,and the former accounted for 55% and the later accounted for 45%.The ratio of one-year leaves and two-year leaves was the same across three kinds of improved varieties.The average length of one-year-old branches was 2 cm ... |
